outputs of electricity eter. A concrete eter ay not co ply with all characteristics
introduced in this anual; however, eter passport defines a precise eter configuration,
possibilities and auxiliary outputs as well as a concrete connection sche e.
The anufacturer has a right to change the infor ation presented in this anual without the
warning. In addition, any copying, trans ission and publication of full or partial eter
docu entation is forbidden without a written per ission of “ELGAMA-ELEKTRONIKA” Ltd.
1 Safety
1.1 Safety requirements
1. Installing, uninstalling, para eterization and verification can be perfor ed only by
authorized organizations that have qualified technicians. Only qualified persons should
install eters.
2. Meter’s connection or disconnection fro network should be done when voltage in the
network is turned off. A protection fro accidental network voltage connection ust be
established.
3. No accessories can be hung on a eter, it is forbidden to hit or strike eter’s case.
4. Precautions ust be taken in battery changing procedure: 1) eter has to be
disconnected fro electricity network, a protection fro accidental network voltage
connection ust be assured; 2) use pincers or si ilar instru ents to change battery
(connection/disconnection of a plug).
1.2 Transportation and storage rules
1. Prior to the usage eter ust be kept in a closed roo in a transportation packing,
where the te perature ranges fro 5°C to 40°C and average area hu idity is up to
80% when te perature being 25°C. The roo ust be without har ful gas or stea .
Meter ust be kept and exploited in pre ises protected fro dust, aggressive vapors
and gas.
2. Unpacked eters can be kept only in repair workshop. The te perature ust range
fro 10°C to 35°C, average area hu idity ust not exceed 80% when te perature
being 25°C.
3. During winterti e eters ust be kept in a heated roo for 6 hours or ore, before
they are used.
4. Meters are to be transported only in closed vehicles (carriage, container, hold). Shake
acceleration is to be up to 30 /s², 80-120 strikes per inute. The te perature ust
range fro -40°C to +70°C, average area hu idity ust not exceed 98% when
te perature being 35°C.

1.3 Prevention and elimination of malfunctions
If suspected that eter works i properly, the following actions should be perfor ed:
1.3.1 Exterior inspection
Before applying voltage to the eter akes sure its case has no echanical da ages, there
are no signs of overheating, and all wires are properly connected.
Do not plug a meter into network if it is mechanically damaged. This can cause
staff injuries and destroy meter as well as other equipment!
Before switching on network voltage, it is necessary to check if sliding voltage
link is connected (see chapter 5.7 Sliding voltage link).
1.3.2 Inspection of connection and parametrization constants
Installing, uninstalling, para etrization and verification can be perfor ed only by authorized
organizations that have qualified technicians. After plugging a eter into electric network
technician should check whether date and ti e are correct, whether eter shows right
energy direction, valid tariff ti e zone and calendar, tariff seasons.
1. If eter shows wrong date and ti e, a representative fro the organization in charge of
the eter installation should be infor ed.
2. If LCD indicator shows a warning note ‘Er’, the eter should be uninstalled and passed
for repair works.
3. If energy direction is wrong, technician should check whether inputs are connected
properly to ter inal block.
4. If eter calendar season, season ti e na e or valid tariff ti e zone does not correspond
to real situation, eter’s para eterization data has to be checked and errors has to be
corrected by repeated eter’s para eterization.
1.3.3 Procedure of meter returning to manufacturer
In case alfunctions cannot be eli inated on the spot, the eter should be returned to the
anufacturer for repair or replace ent. Meters on their return to anufacturer ust have
their Passport with notices of organization in charge of their exploitation and short description
of eter’s alfunctioning.
1.3.4 Proper disposal of product

5 Construction
5.1 Case
Meter case, fixing holes and ter inal block confor to the require ents of standard DIN 43857.
Meter case can be ade fro transparent highly echanically resistant and fire retardant
insulation aterial – polycarbonate, stabilized by ultraviolet rays or olded of non-transparent
polycarbonate with transparent polycarbonate windows for LCD, optical interface and optical test
output. It protects eter interior parts and its na eplate. Main cover (transparent and non-
transparent parts of ain cover) is fixed to the base by two sealing screws. Re oval of ain cover
of ounted eter could be done only after ter inal cover re oval. An option of special sealing
bolts preventing disasse ble of eter is available. Ter inal cover is fastened with 1 sealing screw
(suspended seal). Access to the ter inals without ter inal cover re oval is excluded. This affords
additional level of security to the custo er. Ter inal cover has a hole for threading sealing wire to
sealing screw. The possibility to touch the eter ter inals with sealing wire while sealing the
ter inal cover is prevented.
Figure (See Figure 5-1) presents eter exterior parts and allot ent of control ele ents. For case
di ensions and allot ent of fixing holes see Figure A-0-1.
There is a liquid crystal display (LCD), optical co unication interface, optical scroll key for
display control, sealable and not sealable buttons on the ain cover of the eter. See chapter 11
for the explanation of display control co ands, and chapter 6.10 for the description of push
buttons.

5.2 Nameplate
Na eplate for eter, with transparent cover, is printed on plates ade of PET aterial during the
eter anufacturing process. This ensures that all arks and inscription are clear, non-erasable

17
and non-transferable. Na eplate for eters with non-transferable cover is arked on the non-
transparent part of ain cover by eans of laser arking technology during the eter
anufacturing process. This ensures that all arks and inscription are clear, non-erasable and
non-transferable.
The na eplate bears all the necessary infor ation according to EN 50470-1 and Directive
2004/22/EC, as well as identification of ain data, displayed on LCD. Exa ple of na eplate is
provided in Figure 5-3. Meter serial nu ber is displayed as barcode (by default, barcode type
Interleaved 2/5). Additional QR (DataMatrix) code which contains the eter technical infor ation is

5.3 Terminal block
The ter inal block with all eter connections is situated behind the ter inal cover. Ter inal block
ade fro highly echanically resistant and fire retardant insulation aterial and confor to the
require ents of standard DIN 43857. One utility seal in the fixing screw of the ter inal cover
prevent unauthorized access to the phase connections and therefore also prevent unrecorded
energy consu ption.
Current and voltage ter inals can be ade of zinc-plated iron or nickel-plated brass (copper) and
it provides the ability to add copper or alu iniu wires without oxidation process. Ter inal
assures the sa e quality of the contact irrespective of the shape of the connection conductor (a

5.4 Operation principle
5.4.1 Measurement module
In easure ent odule, current and voltage values of each phase are transfor ed into
proportionally analogous signals.
Precise current transfor ers, shunts or di/dt current sensors are used for current easure ent in
phase circuit. In case eter contains two easure ent ele ents (i.e. type G1B.x6x carries out
current easure ent in neutral as well), current easure ent in neutral circuit is based on
different type of current sensor (current transfor ers or shunts). For voltage easure ent,
resistant voltage dividers are e ployed.
5.4.2 Signal conversion
Analogous signals are transfor ed into digital codes by three-channel Sig a - Delta converter.
Digital signal processor (DSP) calculates average power values P(t) and Q(t), as well as
instantaneous RMS values of current and voltage. Further ore, DSP outputs values of RMS
current in neutral and electricity network frequency.
5.4.3 Micro-controller
By integrating power values, icro-controller accu ulates i port and export energy values.
Energy values are registered to corresponding energy and de and tariff registers in accordance
with the valid tariff progra .
Further ore icro-controller controls liquid crystal display, co unication interface, eter
outputs, tariff progra and internal clock.
5.4.4 Non-volatile memory
G1B eters contain non-volatile flash e ory of different capacity (2048 kB). Flash e ory is
used for data profiles and para eter storage. Me ory retains data for 20 years and ore.
5.5 Display (LCD)
Ga a 100 eters are provided with a liquid crystal display (LCD). The display can be provided
with backlight for easier reading (read chapter 4.8). LCD backlight ay be configured (only by
anufacturer) for one of two work odes and can work per anently or can be switched on by

19
pressing one of the buttons and is extinguished auto atically after a short ti e if no further button
is pressed. LCD backlight can be switched on and turned off locally or re otely.
Default liquid crystal display of G1B eter contains 115 controlled seg ents ( arked in dark
colour in Figure 5-5 - Figure 5-7). Vertical di ension of ain digits is 10 . LCD displays
ajority of data accu ulated in eter and para eterization constants.
LCD divided into 7 infor ation fields which description is not changeable and status indication
fields (▼).
An arrow sy bols (▼) are an additional status indication for load, billing reset block, fraud,
alar , etc. The arrow points to a status description on the na eplate and can be allocated in
different positions for eters with default LCD ( option #1), optional LCD (option #2), and
extended LCD (option #3).
